Yes, anything is possible.
- You can look through the standard Linux SNMP MIBs and use the standards.
- You can create an MIB for the metrics/parameters you need.
In UNIX and Linux, just about anything is possible, BTW.

NAME
SNMP::Info::Layer3::Pf - SNMP Interface to FreeBSD-Based Firewalls using Pf /Pf Sense
AUTHOR
Max Baker
SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $pf = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.
";
my $class = $pf->class();
print "SNMP::Info determined this device to fall under subclass : $class
";
DESCRIPTION
Subclass for Free-BSD PF-Based devices
LLDP Support
LLDP Support is included but untested in this Device Class. It is reported that the available CDP/LLDP modules for net-snmp don't work on
FreeBSD (on which pfSense is based) as they assume certain Linux specific Ethernet structures. This problem is apparently solved on PF
based firewall appliances by using the ladvd package, for which a port may be found here: <http://www.freshports.org/net/ladvd/>. I'm not
sure if this module ties into Net-SNMP or not.
Inherited Classes

See "Required MIBs" in SNMP::Info::LLDP for its own MIB requirements.
GLOBALS
These are methods that return scalar values from SNMP
$pf->vendor()
Returns 'FreeBSD'
$pf->hasCDP()
Returns whether LLDP is enabled.
$pf->model()
Grabs the os version from "sysDescr"
$pf->os()
Returns 'Pf'
$pf->os_ver()
Tries to reference $pf->id() to one of the product MIBs listed above. Will probably return a truncation of the default OID for pf-
based systems "enterprises.12325.1.1.2.1.1".
Global Methods imported from SNMP::Info::Layer3
See documentation in "GLOBALS" in SNMP::Info::Layer3 for details.

$pf->c_id()
Returns LLDP information.
$pf->c_if()
Returns LLDP information.
$pf->c_ip()
Returns LLDP information.
$pf->c_platform()
Returns LLDP information.
$pf->c_port()
